She said: "What the British people voted for on June 23 was to bring some control into the movement of people from the European Union to the UK. A points-based system does not give you that control.

"Because people meet the criteria, they are automatically let in.

"That’s the problem with a points-based system. I want a system where the government is able to decide who comes into the country. I think that’s what the British people want."

Big data online could help create a more targeted immigration system for Britain

Now, the Brexit Alliance have proposed a needs-based system whereby the use of easily available online data to understand the areas of employment Britain needs to improve upon and target the immigration policy accordingly.

It could also highlight areas for improvement within Britain's education or training systems so the country could start tailoring them towards sectors of society, such as the NHS, that might need a specific type of skilled individual – reducing the need for immigration altogether.

A statement from the Brexit Alliance states: "One policy requiring scrutiny, debate and implementation is the UK’s post-Brexit immigration policy, which was a significant factor of the referendum result.

"We propose two approaches to the UK’s post-Brexit immigration policy. Firstly, we believe the Government should approach immigration by determining the real need in the economy and so it should aim for a needs-based immigration policy.

"Secondly, we propose that the Government should determine this need and inform its policymaking more generally by utilising the advances in so-called ‘big data’.

"There has been an exponential increase in the data that is added, stored and available for use online. Correspondingly, there have been major advances in the methods of gathering, analysing and utilising this data, known as ‘big data analytics’.

"The Government and other public bodies can utilise big data analytics to inform policymaking at every stage of its development, from inquiry to debate to drafting and even to its implementation. Thus, enabling a truly evidence-based approach to policymaking.

"Do we need more or less engineers nationally, or in South Wales versus the Midlands, or in London versus Birmingham?

"Do we need less doctors and nurses for the NHS? Can we train our own by promoting already-existing places or funding new ones?

"Do migrants need to earn a minimum amount that then allows them to contribute on a net basis to the UK via tax?

"Big data analytics provides the means to answer these questions and many more, thus setting the foundations for an informed, evidence-based debate and approach to immigration policy—but also policymaking itself—at every stage of its development, including its ongoing implementation."
